Drawings
FIG. 1 is a schematic view of a viscoelastic damper of the present invention.
In the above figures: 1. a connecting plate; 2. a lever; 3. a rigid plate; 4. a curved viscoelastic damping layer; 5. a planar plate member; 6. a planar viscoelastic damping layer.
Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
Embodiment one: as shown in fig. 1, a viscoelastic damper includes a pair of connection plates 1 and a damping module. A pair of connection plates 1 are arranged in parallel with each other with a certain distance, and a damping module is connected between the pair of connection plates 1.
The damping module comprises at least a plurality of rigid plates 3 arranged in a stacked manner and a viscoelastic damping layer formed by viscoelastic materials filled between two adjacent rigid plates 3. The two opposite surfaces of the rigid plate 3 with the largest area are curved surfaces, so that the surface of the viscoelastic damping layer with the largest area is also in a curved surface state, and the curved surface type viscoelastic damping layer 4 is formed.
The damping module may be entirely composed of a rigid plate 3 and a curved viscoelastic damping layer 4. In this embodiment, the rigid plate 3 has an S-shaped longitudinal section, which includes three parallel portions and an arc-shaped portion connecting adjacent two parallel portions. When the rigid plate members 3 are laminated, the arcuate portions thereof are different in size, thereby constituting a damping module in a solid state.
In the damping module, the scheme may also be: the rigid plate 3 is laminated to form a groove, a plurality of plane plates 5 are laminated in the groove, and a viscoelastic material is filled between the adjacent plane plates 5 to form a plane viscoelastic damping layer 6. The planar plates 5 are arranged transversely and/or longitudinally and completely fill the grooves formed by the lamination of the rigid plates 3 to form a damping module in a solid state. In this embodiment, a plurality of planar plates 5 are disposed transversely in the recess formed by the rigid plate 3, i.e. the planar plates 5 are disposed parallel to the parallel portions of the rigid plate 3, and corresponding planar viscoelastic damping layers 6 are disposed. The lengths of the plurality of planar plates 5 are slightly different so that they can fit the rigid plate 3. The planar viscoelastic damping layer 6 is connected only to the surface of the planar plate 5 where the area is largest.
In the above scheme, the connecting plate 1, the rigid plate 3 and the plane plate 5 are all steel plates, the thickness of the connecting plate 1 is the largest, and the thickness of the plane plate 5 is the smallest.
In the above solution, the connection plate 1 is connected to the outermost rigid plate 3 of the damping module by means of a number of rotatable levers 2. The distance between the rotating axle center of the lever 2 and the connecting plate 1 is smaller than the distance between the rotating axle center of the lever 2 and the outermost rigid plate 3, so that the displacement can be amplified, and the energy consumption can be better realized. The position of the rotation axis of the lever 2 is set according to the required displacement amplification proportion, and the multiple of the distance between the rotation axis of the lever 2 and the outermost rigid plate 3 and the distance between the rotation axis of the lever 2 and the connecting plate 1 is the multiple of displacement amplification, for example, the distance between the rotation axis of the lever 2 and the outermost rigid plate 3 is three times the distance between the rotation axis of the lever 2 and the connecting plate 1.
When the vibration is applied, the connecting plate 1 relatively displaces, so that energy is consumed by shearing between the rigid plate 3 and the curved viscoelastic damping layer 4 and between the plane plate 5 and the plane viscoelastic damping layer 6, and the action area is increased by the curved design, so that the damping effect can be improved.
The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
